Product Description

Cheap Fire Fighting dry alarm valve Dry Alarm Check Valve

Introduction
ZSFC dry alarm valve, which is applicable in low temperature environment, is the control valve of dry type sprinkler system. The pipes are charged with gas that generates certain pressure to not only monitor and test the leakproofness but also make the valve keep close. When sprinklers open and the pressure in the pipes reduces to a designed degree, the valve opens, then water runs into the pipimg system and sprays from the sprinklers to extinguish the fire.
